TECHNICAL FIELD

The disclosure relates to the technical field of underwater robots, and more specifically to a pile leg-walking type mining robot.

BACKGROUND

With the rapid development of global economy and increased consumption of resources, land mineral resources are gradually unable to meet the huge demand of people. Therefore, great potential mineral resources from the sea are paid increasingly attention. Underwater robots, as a tool for mining mineral resources in ocean, have made considerable progresses, but still face many practical issues.

Currently, the existing deep-sea manganese nodule mining robots have difficulty walking on the manganese nodule geological layer. The manganese nodule geological layer is soft featured, the direct-bearing mining robots with the manganese nodule present subsidence during operation. The subsidence of the robots causes difficulty in walking, which will directly affect the working efficiency. On the other, hand, the existing deep-sea manganese nodule mining robots do not consider the protection of the benthic organisms during the mining process, which will lead to numerous deaths or even extinction of deep-sea benthos. In deep-sea environment, manganese nodule will continue to grow. However, after being crushed by the walking track, the structure of the geological layer where the manganese nodule is located may be changed, which affects the growth of manganese nodule and seriously destroys the environment of the seabed. Existing deep-sea manganese nodule mining robots are extremely destructive to the marine environment and cannot achieve a reasonable balance between resource mining and ecological protection.

Therefore, how to provide an underwater robot for deep-sea manganese nodule mining which is basically harmless to the benthic organisms, effective protection of marine environment, also with low energy consumption and high mining efficiency is an urgent issue for those skilled in the alt.

In order to further optimize the above technical scheme, an integrated pipe of umbilical cord cable and mineral hose 8 for integrating lines and conveying minerals is connected at the tail of the body 1.

The working principle of the invention, is as follows:

Before the mining robot arrives at the mining area or evacuates from the mining area, it can, be completed by its own buoyancy adjustment mechanism 6 and vector propulsive mechanism 3 in cooperation with the hanging cable of the working boat. In this process, the negative pressure suction mechanism 4, manganese nodule cutter suction mechanism 5 and pile walking mechanism 2 of the mining robot can be retracted to make them as compact as possible and reduce the resistance, as shown in FIG. 4. During operation, the corresponding mechanisms work accordingly.

During the operation of the mining robots, the negative pressure support 43 always works at a certain distance in front of the cutter suction head 53 to safely transfer the benthic organisms in advance. The cutter suction head 53 and suction head of negative pressure pipe 47 make an arc movement at the head of the mining robot, and move forward through the pile walking mechanism 2. The area swept by this arc movement becomes a region, and the mining is carried out in this manner. The width direction of the range that the cutter suction head 53 can sweep exceeds the width of the mining, robot itself, as shown in FIG. 3, so its own walking will not affect the unmined mining area. The integrated pipe of umbilical cord cable and mineral hose 8 is responsible for information exchange and material transportation. The manganese nodules are screened out by the manganese nodule transition treatment cabin 57, and then the manganese nodules are put into the ore conveying hose of the integrated pipe of umbilical cord cable and mineral hose 8, so that the manganese nodules are pumped onto the working ship, and then delivered to the transport ship to the coast or other places. The useless substances screened in the manganese nodule transition treatment cabin 57 are discharged directly, which makes them return to the mining area directly and reduce the energy consumption of secondary regression. The setting of three lifting piles 22 can not only meet the operation stability of the mining robots, but also reduce the energy consumption of other auxiliary stabilizing devices.

During the operation of the mining robot, the pile walking mechanism 2 replaces the traditional track through lifting pile 22, and such point support excellently protects the deep-sea environment. The feeding hydraulic cylinder 212 can rotate vertically around the body 1 of the mining robots. When the feeding hydraulic cylinder 212 is in the horizontal direction, as shown in FIG. 2, the lifting pile 22 stands upright on the seabed, and the lifting part 213 can adjust the vertical movement of the lifting pile 22, so as to adjust the height of the mining robot, body. When the mining robot performs a feeding movement, the lifting part 213 makes the lifting pile 22 move up and down step by step to complete the movement.

Specifically: the robot has three piles, which is similar to three legs. The lifting component 213 controls the lifting and falling of the lifting pile 22, and the feeding hydraulic cylinder 212 controls the lifting pile 22 to move forward and backward of relative to the mining robot body 1. The lifting pile 22 is firstly raised and suspended under the control of lifting component 213, and then the hydraulic cylinder 213 is fed to retract the piston rod. The lifting pile 22 moves forward for a certain distance relative to the body 1 of the mining robot and stops. Then the lifting component 213 controls the descending of the lifting pile 22 and inserts it into the hard soil geological layer 94. This is one step ahead of the lifting pile 22 and corresponds to the mining robot. At this point, the lifting pile 22 has been advanced by one step relative to the mining robot, which is equivalent to a step forward. When all three lifting piles 22 take a step forward, the three feeding hydraulic cylinders 212 simultaneously extend the piston rods. The movement of the lifting pile 22 is restricted in the hard soil geological layer 94. Therefore, the robot body 1 moves forward with respect to the lifting pile 22, moving forward with respect to the ground, thus completing the walking process.

The system is equipped with three sets of pile walking mechanism 2, which can move horizontally under the control of feeding hydraulic cylinder 212 and coordinate with each other by alternating lifting and retracting to complete the feed movement of mining robot and make it move forward. The forward motion is supported by lifting pile 22, which has a very small rolling area. Three lifting piles 22 can make them stand firmly on the deposit and precisely mine the mine area.
